The problems that I have read about are mostly related to the grip flexing and losing contact with the camera, thus the camera switching off.
When the 20D was brought in as a replacement to the 10D the battery grip was redesigned as the 20D is smaller and so the grip had to marry up. Canon moved the retaining screws (not the one that screws from the grip into the camera) closer to the centre of the new grip and this allowed some extra flex that was not apparent in the 10D’s grip.
The screw that attaches the grip to the camera also has been reported to work lose, the problem with that is as CT has stated in that it doesn’t do it slowly, its either tight or lose and gives no warning in between. Obviously that again adds to the flex problem and inevitably the camera and grip losing contact resulting in the camera losing power.
There are also reports of this new grip not giving correct readings for the remaining battery power. These reports are a lot fewer than for the flex problem but there are still enough for it to indicate it to be a real issue and not something that just one batch was suffering from. Obviously all you need to do is carry extra batteries (which most of us do anyway) but why Canon managed to mess up such a simple product that was previously almost perfect is still a mystery.
Ref Canon and the problem..last time I checked Canon UK had not acknowledged the issues yet Canon USA had. They issued an upgrade/modification/repair that basically placed two washers on the inside of the grip to spread the weight and reduce the flexing. I also believe that this modification has now been included at the production stage so getting a latest batch grip should be better if not perfect.
As to the battery problem, I have not managed to get any definitive answer.
Hope that helps?
